Contrary to the often expressed belief, owning guns in the UK is not that difficult.
My first gun was a Winchester 140 semi auto shotgun that my parents bought for me when I was 16. I traded it in about 8 years later to buy high capacity Remington 1100.
My next guns were all pistols which sadly have been melted down by the Government after they were banned.
But now the rifles I own are a Ruger 10/22, Calico M100, 9mm AR, .44 mag Marlin 1894P, .45 Delisle silent carbine, .303 SMLE, .223 Browning BLR
Shotguns , Remington 1100, Remington 870, Beretta 686, Mossberg 930 and Ithaca Mag 10
And a couple of long barrel pistols that avoid the ban, .22 Browning Buckmark & Taurus .44 mag revolver.
If anyone in the UK wants to take up target shooting it's really quite simple to do so.
